GPI-32 General Purpose Input Interface Installation and Operation Manual
DESCRIPTION
Product Description
The GPI-32 interfaces 32 optically isolated inputs to a users PC's RS-232 or USB
port. The serial data conforms to our standard audio switcher PIP format. The
GPI-32 is equipped with dual plug-in euroblock screw terminals and two independ-
ent DB-37 connectors that may be interfaced directly to the DB-37 connectors locat-
ed on the StarGuide II/III, XDS OR WW1-MAX relay cards. Additional features;
dual RS-232 connectors, one for daisy-chaining multiple units on the same legacy
serial port and a DB-9 to interface to our supplied USB to RS-232 adapter; LED
indicators for power and input activity; twin power connectors allowing up to four
units to be driven off of one power transformer. The GPI-32 is supplied with USB-
RS-232 adapter cable, RJ-11 cable and “S9” DB-9 female adapter and 9vac wall
transformer. The GPI-32 is powered by a surge protected internal power supply.
The GPI-32 may be rack mounted via the optional 1-RU, RM-3 mounting shelf.

INSTALLATION
Installation Guidelines
Please examine your GPI-32 carefully for any damage that may have been sustained
during shipping. If any is noted, please notify the shipper immediately and retain the
packaging for inspection by the shipper. The package contains the GPI-32, 9 VAC
@ 1 amp wall power transformer, USB-RS-232 Smart adapter cable, RJ-11 cable and
“S9” DB-9 female adapter, DB-9 straight-thru serial cable and this manual.
NOTE: All connections are noted on the top cover label.
Input connections:
The two plug-in euroblock screw terminals (TB-1 & 2) are labeled “Inputs” 1 thru
16 and “Inputs” 17 thru 32. The last two screw terminals (17 & 18) on each plug-in
euroblock are the ground connections. Each input is optically isolated and inter-
nally power by 5 vdc. Connect your equipment to the appropriate screw terminal
and either of the GND terminals. Contact closures, TTL logic and/or open collec-
tors may be used to activate each input. A valid input must be 40ms or greater and
is indicated by a “wink” on the “DATA’ led.
NOTE: The two female DB-37 connectors are designed to directly mate to the
StarGuide II/III relay card connector via the supplied cables. The pin-outs for
the DB-37’s are listed below.

Pins not used on both J5 & J6: Pins 5, 10, 15, 24, 33
CAUTION!
Installation of the GPI-
32 in high RF environ-
ments should be per-
formed with care. It is
recommended that all
cables connected to the
GPI-32 be looped
through ferrite cores to
suppress RF. Surge
protection with RF fil-
tering such as the
Tripp-Lite “ISOBAR 4
or 6” is also suggested
for the wall trans-
former. Shielded cable
is suggested for all
input connections. The
shields and station
ground should be tied
to the “CHASSIS
GROUND” screw ter-
minal. For lightning
protection devices,
check out
www.polyphaser.com
and www.itwlinx.com.

INSTALLATION
RJ-11 Serial connector:
The GPI-32 is supplied with the “S9” RJ-11 to DB-9 female adapter and RJ-11 four
conductor X-Over cable. We supply this cable for normal serial operation or in
case multiple GPI-32’s are used with the users PC.
DB-9 Female Serial connector:
The female DB-9 connector is provided for customers wanting the use a user pro-
vided straight-thru serial cable to connect to the COM port of their PC. The sup-
plied USB-RS-232 adapter cable should be attached to this connector if USB oper-
ation is required.
USB-RS-232 Adapter Cable:
The Smart USB to RS-232 adapter cable is provided for customers needing to use
the USB port supplied with their PC. Remove the smart adapter cable from the
packaging and follow the installation instructions provide with the adapter cable.
When the smart adapter is operating, connect the USB connector to the PC and the

*uSPii - Send status of input ii. Response is SuP,ii,x<cr><lf > where x is 0 if
the corresponding input is high (OFF), 1 otherwise (ON).
*uSPA - Send status of all inputs. Response is
SuP,A,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x--> 32<cr><lf > where input 1 is

*POLL - Respond with unit (ID) address in appropriate time slot. If there are
multiple units on the line, each will respond with a different delay
after receipt of this command.
CAUTION!
The top cover of the
GPI-32 must be
removed to gain access
to Dipswitch SW1.
Remove all connections
and power before
removing the cover. To
remove the cover,
remove the two cover
screws. Lift the cover
and stow the cover and
screws in a safe loca-
tion. Make the
changes to SW1 and
reinstall the cover and
screws. Connections
may now be reapplied.

The 16 status/logic inputs may be activated either by pulling
the input to ground or releasing the input to a high state. External
sources can be contact closures, open collectors or 5, 12, 15,
and 24-volt logic-level sources. The input impedance of each
input is 22 K ohms. Supplied with plug-in Euroblock connectors.
